Title: Improvements in or relating to plant for packing edible fat and the like
IPC: B65B61/28
Filed: 1933-01-20
Abstract: 393,894. Endless-belt conveyers stepby-step conveyers. HESSER MASCHINENFABRIK AKT.-GES., F., 99, Olgastrasse, Cannstatt, Stuttgart, Germany. Jan. 20, 1933, No. 1883. Convention date, Feb. 17, 1932. [Class 78 (i).] In a plant for packing edible fat, hollow receptacles containing the filled packets travel in transverse rows through a cooling chamber, and each row of receptacles in turn is brought on to a conveyer which delivers them singly to a packet-sealing machine. After sealing, the packets are ejected from the receptacles, and the latter are conveyed to a packet-making machine working in step with the sealing machine for the insertion of fresh packets and thence to the filling station. The receptacles b are of the form shown in Fig. 11, provided at the base with an opening f and upstanding edges d. In one arrangement, rows of receptacles leaving the cooling chamber in an upright position are drawn by hooks 51, Fig. 4, engaging the edges d on to a lifting rail 53 by which they are carried up a curved wall 56 and placed in a recumbent position on a conveyer 60 moving forward intermittently in step with the packetmaking and sealing machines. The receptacles are transferred from the conveyer 60 by means of a rocking lever 70, Fig. 7, to a lowering conveyer 65 and thence to a conveyer 75 beneath the conveyer 60 and moving in the reverse direction, the receptacles being advanced intermittently along a pair of stationary rails 92 by fingers 75a carried by a rod 79, Fig. 8, to which is imparted a circular motion made up of a to and fro movement provided by a rocking lever 81 and an up and down movement communicated through the bearing bushes 85, 86 by cranks 90, Fig. 6. The sealing machine S, Fig. 5, comprises a number of devices arranged at points along the conveyer 75, the projecting ends of the packet a being folded, gummed and pressed down in a series of steps. At the point VII, the sealed packets a are ejected from the receptacles b on to a track 181 by a pusher 180 which passes through the apertures f, while the empty receptacles are carried on to the packet-making machine P, where fresh packets are inserted. At the end of the conveyer 75, the receptacles are pushed by auxiliary fingers 75b on to a rocking lever 185, Fig. 6, somewhat similar to 53, Fig. 4, which deposits them in an upright position on a conveyer 190 for transfer to the filling station.

Title: Improvements in insulated boxes or cases for the transport and storage of ice-cream or other material affected by heat or cold
IPC: F25D3/14
Filed: 1931-01-20
Abstract: 366,264. Refrigerators. BUTTERFIELD, C. S., Sobraon Works, Bow Common Lane, London. Jan. 20, 1931, Nos. 1903 and 25836. [Class 29.] A portable box for transporting and storing ice cream &c. comprises an outer case having side panels a and a base of plywood or hardwood, a galvanized metal lining n, and insulation o between the lining and the case. The side panels are secured at their upper and lower ends respectively to wooden frames d, h, e and the base is secured to a wooden frame k carrying iron skids r. The lining is secured at its upper end by a flange p to the underside of the frame h which is recessed to accommodate a packing ring i and the wooden frame t to the cover s, the underside of which carries a metal container for insulation and a perforate box 2 for solid refrigerant, e.g. carbon dioxide. In a modification, the refrigerant is stored in a case having hinged lids 9, Fig. 6, and a perforate tube through which the vaporized refrigerant flows into the box. In another arrangement, a rectangular tube having outlet openings in one of its sides is arranged at one side of the case. In a further modification, the vaporized refrigerant flows out of the case 15, Fig. 10, into an apertured duct 13 formed in the lining of the storage box.

Title: Improvements in valve-actuating mechanisms for actuating fluid-control valves in timed sequence
IPC: F15B13/06
Filed: 1959-01-19
Abstract: 903,540. Valves. LYNCH CORPORATION. Jan. 19, 1959 [Jan. 20, 1958], No. 1904/59. Class 135. A welded housing 18 with a base-plate 12 and hinged cover 20, that may be opened against the action of spring catches 26, enclose a shaft 30, driven from a glassware forming machine (not shown), upon which is mounted a drum 28 incorporating one or more annular grooves 38 in each of which is adjustably located two pins 40, 42 of different lengths. Aligned with each groove 38 and supported upon the plate 12 is a valve body 54 housing a piston closure member 62 in a sleeve 60, which member controls the flow of fluid from a manifold 68 past an adjustable throttle 75 to a single-acting piston 84 actuating a part of the machine, and exhaust from the piston 84 via another throttle 90 to a manifold 96. If the piston is double-acting another control land is formed on the closure member. In the inoperative position the member 62 is elevated by its spring 64 to connect the piston 84 to exhaust; the drum 28 rotates clockwise so that the shorter pin 40 firstly depresses the member 62 and enables a spring- loaded plunger 102 to overlie a shoulder 126 and latch the member 62; in this position pressure fluid is directed, as shown by the arrows, to the piston 84. The longer pin 42 now engages and further depresses the closure member but no change in the fluid flow results; further rotation of the drum results in the pin 42 retracting the plunger 102 whereupon the spring 64 elevates the member 62 into the inoperative position. The cycle is repeated when the drum again brings the pins 40, 42 into engagement with the closure member 62. Each closure member is provided with a manually-operated spring-loaded catch whereby it may be locked in the retracted position.

At least one further such edging member may be joined to the panel so that the edging members form a frame, e.g. of a cabinet, the bonding agent preferably serving also the joining the edging members together. Other fitments, e.g. a hinge anchorage may be similarly secured to the panel. The edging member may be of steel, e.g. coated with PVC aluminium, polystyrene, PVC or cardboard; the bonding agent may be a thermosetting or a thermoplastic material, e.g. a liquid polyester, epoxy resin or polyurethane composition or based on wax or bitumen; and the panel may be a metal sheet or a laminate comprising a foamed polyurethane core 19 between a polypropylene sheet 17 and a paper sheet 18 as shown or a polypropylene sheet adhesively bonded to a compressed wood pulp board (Fig. 3, not shown). As shown the panel 3 is slit at 20, 21 so that it can be folded to form inner side and base walls of a cabinet and is provided with recesses 23 in which is bonded by the plastics body 6 support plates 5 of sheet steel. Channel pieces 4 also of steel may be provided as reinforcements in recesses 22 in the panel and along the panel fold lines. A decorative outer finishing plate 7 may be attached by its flanges 30, 31 to the bottom and rear faces of the cabinet with its edge 29 located in the groove 28 of upright member 8.

Title: Improvements in or relating to evaporator apparatus
IPC: B01D1/26
Filed: 1923-01-22
Abstract: 217,945. Flint, L. R. Jan. 22, 1923. Multiple-effect apparatus; bulk evaporators; separate heater and evaporator apparatus.-In evaporating-apparatus in which the liquid circulates through a heating-device, the heated liquid is passed, prior to its return to the heating device, through a chamber in which a considerable surface of liquid from which evaporation takes place is formed. The chamber may be formed inside or separate from the head of the evaporator. Circulation of liquid is effected by gravity or by a pump. As shown in Fig. 4, applied to multipleeffect apparatus, each effect comprises a vertical tubular heater, surmounted by a chamber a<1> from which vapour passes through perforations p and liquid through an opening o into an annular chamber F. The liquid is caused by a partition n to pass round the chamber to a pipe g by which it is returned to the base of the heater. The liquid to be evaporated is, prior to its entry into the multiple-effect apparatus, passed through a chamber D maintained under vacuum to remove incondensible gases and is then fed either through a valve 5 to the effect C of lowest pressure or by a pump 10 to the effects A, B, of higher pressures. Pumps 10, 23, 36 serve to assist circulation of the liquid through the effects and also to feed liquid from effects of lower pressure to those of higher pressure. Pipes 28, 30, 32 serve to feed liquid from effects of higher pressure. to those of lower pressure. Valves 8, 21, 27 enable liquid to be withdrawn from any effect. The effects may be placed on different levels so that liquid may be fed to effects at higher pressure without the use of pumps.
